What Is Anti Reflective Coating?
Anti reflective coating, also known as AR, anti-glare, no-glare, or glare-free coating, can provide benefits to your vision. Anti reflective coating is added to lenses to reduce glare caused by light hitting the back of the lenses to improve your vision and make your eyeglasses more visually attractive.
Anti reflective coating will eliminate all reflections from the front and back surfaces of your lenses. Hence, more light is able to pass through your lenses which improves your vision. At the same time, fewer distractions are visible and the lenses are hardly noticeable, especially in the dark. So, is anti glare worth it? Most people agree that.
Cyxus Blue-Light-Blocking Glasses for Kids
So the price you pay for a pair of blue light blocking lenses depends more on the quality and style of the frame than on the effectiveness of the lens. The glasses, which come in a black and pink frame, come with a waterproof case in the shape of a rabbit, a cleaning cloth, and a blue-light flashlight to test the lenses. The brand's boxes come in very cute kids' colors and shape to make it fun. (In addition to the all-black version, there are blue, green, and red versions.)

Repair your old eyeglasses.
Whether it's a scratch in the lens, a dent in the frame, or a missing screw, it's possible to get your glasses fixed and save you a lot of money. In America, a small screwdriver in an optical store, an electronics store, or even a Christmas cracker is enough to help. Or you can run some thin wire through the hole where the screw is, then use some pliers to wind the wire around the inside of the frame a few times, and then use the pliers to screw the ends together. You can use commercially available scratch repair kits to fix scratches on your lenses, or you can use household products like toothpaste or baking soda to polish and remove scratches. If you don't have time to do it yourself, you can call a professional to fix it.
Benefits of Progressive Lenses
Progressive lenses are different from traditional reading glasses and bifocal glasses in that bifocal reading glasses have to constantly change the focal length, causing fatigue. And there is no clear dividing line between the two focal lengths. They are more comfortable, more beautiful. When you see far or see near, a pair of glasses can be done, so they become the best choice for old people little by little.
Progressive lenses allow multiple fields of view to be merged into a single lens with no discernible difference between the fields themselves. Degrees of the lens vary gradually from far to medium to your full reading. This is why progressive lenses are often regarded as no-line bifocals or trifocal points.

What is blue light?
To prevent blue light, we must first understand what blue light is. The visible light with a wavelength range of 400-500 nanometers is called blue light. The light sources used in daily LED lighting and display products, including mobile phones, flat panels, and TVs, are mostly LED light sources excited by blue light. However, not all blue light is harmful to the human body. The human eye has an extremely low tolerance to blue light radiation in the 400-440 nanometer range. When the light intensity enters this threshold, photochemical damage is likely to occur. However, blue light radiation in the range of 459-490 nanometers is essential for regulating the human body's circadian rhythm and can affect the secretion of human melatonin, which in turn has an impact on the body's biological clock, alertness, and mood.
Scientifically effective anti-blue light lenses must not only block harmful blue light but also cannot filter beneficial blue light. Most of the ineffective anti-blue light products on the market currently have two types of problems. One is that there is almost no protective effect on the blue light in the vulnerable zone of the human eye. The other is excessive protection, shielding the blue light spectrum in the beneficial band so that the blue light that is beneficial for physiological adjustment cannot enter the human eye. At the same time, the color of the lens is yellow, which is prone to color shift, aggravating visual fatigue, and even inducing the risk of myopia.
